NOMINAL VOLTAGE = PHASE - PHASE
100...241500 V
Function of the setting of nominal voltage is to make a definition
about the nominal voltage of the system. The threshold levels for
under- and overvoltage are based on this as well as the ratings of the
capacitor sizes in step database, which are used for control and
monitoring. The capacitor sizes, which are stored in step database,
are also rated to the nominal voltage.
202
CT-FACTOR
1...9600
The CT FACTOR is the ratio of current transformer.
(e. g. 1000/5 = ratio 200).
At devices with software version 1.04 is the adjustment range from
1-4000.
203
VT-FACTOR
1...350
VT FACTOR is the ratio of the voltage transformer.
If the regulator is connected directly to the measurement voltage
without VT the value 1 has to be used.
204
V-TOLERANCE
0...100 %
The setting of this value is in percent related to the nominal voltage.
By means of the set value, the upper and lower limits of the
permissible voltage range are calculated. e.g. 10% at 400V nominal
voltage is a permissible range from 360V to 440V.

CONNNECTION MEASUREMENT
Yes/No
"YES" voltage measurement L-L
"NO" voltage measurement L-N
CONNECTION MEASUREMENT the setting if measuring of voltage is
connected between two phases or between phase and neutral
phase. It is normally detected automatically at every start of BLR-CM.
This is done by comparing the setting NOMINAL VOLTAGE and the
real measured voltage. This cannot be changed by hand.
If the measured voltage is outside this tolerance, the measurement
can be adjusted by hand.
